    Hi all, I want to write a simple app to monitor a game's framerate and I need some help w/ RTSS SDK. How do I get the focus game's framerate?

    I see the fields in the mem struct etc. but how do I actually get it to detect the focused game and populate the app struct w/ the right game+framerate info?
    Not really seeing how to do this from the SDK info :bang:

    Thanks in advance, gpk

    (cannot post in the advanced sub-forum yet so please feel free to move this thread or if someone can cross-post there)

    Sorry for delayed reply, I just came back from vacation. That's how it is implemented in MSI Afterburner hardware monitoring graph:

    Code:
    float CMSIAfterburnerMonitoringSourceFramerate::GetData()
{
	float result	= FLT_MAX;
	m_strGroup		= "";
			
	HANDLE hMapFile = OpenFileMapping(FILE_MAP_ALL_ACCESS, FALSE, "RTSSSharedMemoryV2");

	if (hMapFile)
	{
		LPVOID pMapAddr = MapViewOfFile(hMapFile, FILE_MAP_ALL_ACCESS, 0, 0, 0);

		LPRTSS_SHARED_MEMORY pMem = (LPRTSS_SHARED_MEMORY)pMapAddr;

		if (pMem)
		{
			if ((pMem->dwSignature == 'RTSS') && (pMem->dwVersion >= 0x00020000))
			{
				HWND	hWnd		= GetForegroundWindow();
				DWORD	dwProcessID	= 0;

				if (hWnd)
					GetWindowThreadProcessId(hWnd, &dwProcessID);


				for (DWORD dwEntry=0; dwEntry<pMem->dwAppArrSize; dwEntry++)
				{
					RTSS_SHARED_MEMORY::LPRTSS_SHARED_MEMORY_APP_ENTRY pEntry = (RTSS_SHARED_MEMORY::LPRTSS_SHARED_MEMORY_APP_ENTRY)((LPBYTE)pMem + pMem->dwAppArrOffset + dwEntry * pMem->dwAppEntrySize);
	
					if (pEntry->dwProcessID)
					{
						if ((pEntry->dwProcessID == dwProcessID) || (result == FLT_MAX))
						{
							if (GetTickCount() - pEntry->dwTime1 <= 2000)
							{
								if (pMem->dwVersion >= 0x00020005)
									result = pEntry->dwStatFrameTimeBufFramerate / 10.0f;
								else
									result = 1000.0f * pEntry->dwFrames / (pEntry->dwTime1 - pEntry->dwTime0);
							}
							else
								result = 0;

							if (pEntry->dwFlags & APPFLAG_DD)
								m_strGroup = "DD";

							if (pEntry->dwFlags & APPFLAG_D3D8)
								m_strGroup = "D3D8";

							if (pEntry->dwFlags & APPFLAG_D3D9)
								m_strGroup = "D3D9";

							if (pEntry->dwFlags & APPFLAG_D3D9EX)
								m_strGroup = "D3D9E";
							
							if (pEntry->dwFlags & APPFLAG_D3D10)
								m_strGroup = "D3D10";

							if (pEntry->dwFlags & APPFLAG_D3D11)
								m_strGroup = "D3D11";

							if (pEntry->dwFlags & APPFLAG_OGL)
								m_strGroup = "OGL";

						}

						if ((dwProcessID == pEntry->dwProcessID) || !dwProcessID)
							break;
					}
				}
			}
			else
				result = 0;

			UnmapViewOfFile(pMapAddr);
		}

		CloseHandle(hMapFile);
	}

	return result;
}
